The petitioner, Thomas F. Dowd, appeals from a judgment of a single justice of this court denying the relief he sought in a document that the single justice treated as a petition under G. L. c. 211, § 3.1 We affirm.
Dowd’s petition disputes the legality of certain conditions of probation imposed on him in an underlying criminal matter.2 Because the propriety of those conditions can be adequately challenged in the ordinary appellate process, and Dowd has neither alleged nor demonstrated otherwise, the single justice did not err in denying extraordinary relief under G. L. c. 211, § 3.3 See, e.g., Constantine v. Commonwealth, 435 Mass. 1011, 1012 (2002).
Judgment affirmed.
